IMPROVEMENT IN UMBRELLA-RUNNE'RS.

Specication forming part of Letters Patent No. 200,609, dated February26, 1878; application filed January 17, 1878.

.ToA all whom t may concern:

Be it known that I, HENRY S. FROST, of Watertown, county of Litchfieldand State of Connecticut, have invented a new and useful represent theblank in various stages of manufacture, and Figs. 6 and 7 the finishedartic e.

To enable others skilled in the art to make and use my invention, I willproceed to describe iully the method which I have devised for producingthe same.

A, Fig. 1, represents a flat disk of metal, preferably of brass, whichis rst drawn in the usual well-known or any other proper manner, asindicated in Fig. 2, until a tube, a, Figs. 3 and 3, is formed of theproper diameter for the head of the runner which is to be made.

The part designed for the Cylinder portion is then further reduced insize,.as shown in Fig. 4, in a similar manner until its proper diameterhas been reached. The head of the Arunner is then crimped, as indicatedin Figs. 5 and 5a, by any suitable means to form an A horizontalvgroove, c2, Figs. 6 and 7', is then formed in the head by means of asaw, for the reception of the binding-wire for securing the stretchersin place. A

By the employment of themethod described a runner is obtained which is asingle .solid structure, instead of being composed of' several pieces,as has been the case heretofore. By means of this method, also,'ahighlyiinished runner may be readily made-a result impossible'to beaccomplished with the old forms of construction. By means of thismethod, also, the labor and cost of making the runner are materiallyreduced.

I am aware of the patent of A. G. Davis,

No. 75,881, March 10, 1868; but the runner i secured by this is not madein a single piece. I am also aware that a differently constructed runnerhas been made in a single piece by a different method.

Having thus described my invention, Iclaim and desire to secure byLetters Patent- 1. The described method of making the runner,consisting, essentially, irst, in drawing a metal disk into a tube withan enlarged head 5 secondly, crimping the head to form the verticalnicks al and,thirdly, sawing the horizontal groove a2.

2. As a new article of manufacture, a runner made in one piece, havingan enlarged head provided with the crimped vertical nicks and thehorizontal slots, as set forth.

This specification signed and witnessed this 8th day of January, 1878.

HENRY S. FROST.
